I have snow leopard installed on my MacBook from early 2007 (with trackpad that included a separate button). Before, I used to two-finger-tap my trackpad as a way to use its "right click" option. And I restore the system yesterday.Now it only seems to work when I place two fingers on trackpad "and click the button".

Is there a way to restore this to the old settings? I can't find it within the Trackpad Preferences. The only option I can click on is "For secondary clicks, place two fingers on the trackpad and click the button"
